WPF: Create a dialog / prompt

Question

I need to create a Dialog / Prompt including TextBox for user input. My problem is, how to get the text after having confirmed the dialog? Usually I would make a class for t

I just add a static method to call it like a MessageBox:

And the code behind:

public partial class PromptDialog : Window
{
    public enum InputType
    {
        Text,
        Password
    }

    private InputType _inputType = InputType.Text;

    public PromptDialog(string question, string title, string defaultValue = "", InputType inputType = InputType.Text)
    {
        InitializeComponent();
        this.Loaded += new RoutedEventHandler(PromptDialog_Loaded);
        txtQuestion.Text = question;
        Title = title;
        txtResponse.Text = defaultValue;
        _inputType = inputType;
        if (_inputType == InputType.Password)
            txtResponse.Visibility = Visibility.Collapsed;
        else
            txtPasswordResponse.Visibility = Visibility.Collapsed;
    }

    void PromptDialog_Loaded(object sender, RoutedEventArgs e)
    {
        if (_inputType == InputType.Password)
            txtPasswordResponse.Focus();
        else
            txtResponse.Focus();
    }

    public static string Prompt(string question, string title, string defaultValue = "", InputType inputType = InputType.Text)
    {
        PromptDialog inst = new PromptDialog(question, title, defaultValue, inputType);
        inst.ShowDialog();
        if (inst.DialogResult == true)
            return inst.ResponseText;
        return null;
    }

    public string ResponseText
    {
        get
        {
            if (_inputType == InputType.Password)
                return txtPasswordResponse.Password;
            else
                return txtResponse.Text;
        }
    }

    private void btnOk_Click(object sender, RoutedEventArgs e)
    {
        DialogResult = true;
        Close();
    }

    private void btnCancel_Click(object sender, RoutedEventArgs e)
    {
        Close();
    }
}

So you can call it like:

string repeatPassword = PromptDialog.Prompt("Repeat password", "Password confirm", inputType: PromptDialog.InputType.Password);
